Soundmachines NS1 Nanosynth Mini Modular Synthesizer and NS1 Exmperimenters Kit
Note: links to listings are affiliate links for which the site may be compensated.

"The NS1nanosynth synthesizer is an handeld 220x85mm analog modular synthesizer coupled with an Arduino Leonardo platform.
Power Supply is 5v/160mA either from the USB micro connector or the classic 5.5mm barrel jack, central positive. If you use use both concurrently, power will be drawn from the barrel jack.
Feeding the NS1 with more than a regulated 5V will result in immediately destruction of most part of the product (i.e. holy smokes + swears).
On board the synth, +12 and -12 voltages, necessary for the oscillator and the filter, are generated through a DC/DC module.
All CV control signals are 0-5V unipolar. Oscillator waveforms outputs are equally 0-5V to be able to use the on board modules to mix cv and audio signals without problems (see the ‘waveshaping’ video for an example of this)."

Dungeon Synth on Digitone II - Oggol's Sigth
video upload by Silent Tower
"I'm continuing my experiments with sound. And every time I find inspiration in plastiboo books. Such potential is hidden in them. Recently, I also got 'GodHusk' in addition to 'Vermis I' and 'Vermis II'. Although it's not as popular, it's also a masterpiece, and I'm sure I'll use it in the future to find inspiration.

"Universal Sequencer on the right is master and the one on the left is synced to it. Otherwise it’s an equivalent of two Synthi AKS playing side by side. No additional effects used."

Sampling my meditation class over old school trance feat Roland TR-1000, S1 & P6 Compact, Hydrasynth
video upload by Luke Neptune
"I was messing around and came up with this nostalgic old school trance jam. Then I had the idea of sampling my voice from one of my meditation classes and added it in.
This is the result. I hope you enjoy it and happy new year to you all."

MARS Tube Synthesizer vs Ultrarare Formanta P432 VST Plugin
video upload by Eternal Engine EMI
"Our friends from UltraRare ( https://ultrarare.su ) have created a cool plugin: a VST version of the Soviet Formanta P432 synthesizer.
The plugin is a rompler with sounds from this Soviet synthesizer. One of the features of the software version is the ADSR envelope, which expands the instrument's sonic capabilities. The sound bank is controlled via MIDI, allowing users to freely switch between presets within a single part.
There's a lot more interesting stuff on the UltraRare page: https://ultrarare.su/?post_type=product"
Designing and troubleshooting a module | Instruō - ceithir
video upload by Instruō
"Hello and welcome!
👉 • Instruō - ceithir | Project Overview
(Here is an introduction to the ceithir with more detailed project background and sound examples.)
In 2015/16 Instruō began as a video project. Specifically a time-lapse of me designing the original troika module.
Ten years later, I’ve returned to that idea with ceithir, a winter holiday project I designed with video documentation in mind.
This video shows the process of ceithir's initial prototype design.
The full module interface was the first part of the process. That stage has its own video feature:
• Designing a Eurorack Module interface | In...
In this first hardware iteration I focussed on the core functionality of a single channel version of the filter. The majority of the circuit was tried and tested in the I-ō47 module. But I made several additions to the design for ceithir:
Temperature compensation of the core
Dedicated oscillator mode with stable peak amplitude
Stereo output utilising modulated phase shift to create discreet L/R
Additional mode morphing to incorporate band-pass response
I forged ahead with a hardware design where priority was not placed on manufacturability of the prototype. It is a two board layout requiring circuitry distributed between two parallel PCBs. This used many header connectors but provided a large "canvas" to lay out all elements of the circuitry in a sectional way that allowed for ease of navigation when it inevitably came to troubleshooting and fixing mistakes/making refinements.
